The Martial Unity
chapter-1364

"This is an example of sympathetic resonance." The professor had instructed back then with a mundane tone. "Measure the distance, frequency, and amplitude and note them down in a table in your lab journals."

If anybody had told young John that he would one day be using this principle to create a fighting technique to kill other Martial Artists, he would have looked at them with a strange expression before moving away.

But it came to be.

Rui's idea was simple. The principle of sympathetic resonance allowed for one to pass on vibrations to a target through sound as long as the frequency of the vibrations matched the innate vibrating frequency of the target. Every object had an innate vibrating frequency, it was possible to vibrate an object and even cause it to generate force as long as said was exposed to sound of the same frequency.

In fact, this was the same principle that was used in MRIs, lasers, and even electrical circuits.

'And also, in Martial Art techniques. Hopefully.' Rui mused.

It was one of the reasons he was trying to improve his pitch control in the same way that musicians trained their pitch.

His goal was simple. If making sound attacks too weak to be detected also made them too weak to hurt Martial Seniors, then he could bypass the latter using sympathetic resonance.

Every object, including Martial Bodies, had an innate vibration frequency. If he could launch sound attacks with the same pitch as the innate vibration frequency of his opponent, then he could completely bypass their defenses by causing their bodies to vibrate, inside and out.

Their durability or defenses would be helpless since the innate vibration frequency could serve as a clear chink in their armor, allowing Rui to propel his sound attack right past their defenses with no problem.

Once the sound attack traveled past their exterior, he could use it to attack particularly vulnerable places like their heart or brain. If he could do that, then...

'It would mean instant death, most likely.'

Through this way, he could make Squire-level attacks bypass quasi-Senior level defenses, and bypass passive baseline Senior-level senses.

The principle of this technique was similar to that of Reverberating Lance. However, there was a crucial distinction. Reverberating Lance produced vibrations, not sound.

Not all vibrations were sound, and sympathetic resonance only occurred through sound.

In reality, it was extremely difficult to use Reverberating Lance to generate sound in the air. Even for the Martial Body, moving his fist back and forth so rapidly that it was indistinguishable from intense sound, passing onto the atmosphere as sound, was impossible.

'Though I haven't tried doing that with the Martial Heart yet.' Rui noted.

He immediately put it on his to-do list.

A lot of technique ideas that were perhaps impossible to accomplish in the Squire Realm were now potentially possible with the power of the Senior Realm. It was perhaps possible to upgrade other techniques in such a manner.

For now, however, Rui was content with developing a technique that could allow him to assassinate Martial Seniors with ease. The issue was that it was not going to be easy, and certainly not going to be without its own constraints.

One big impediment even if he did succeed in developing such a technique was the fact that he needed to not only know what the innate vibration frequency of his opponent was but also needed to master the ability to be able to generate that same frequency with his Mighty Roar Flash Blast.

Those two conditions required him to gain a deep understanding of pitch. Which was why he had immediately begun mastering pitch. Once he gained perfect pitch, then he could focus on identifying and mastering the right frequency for each target.

'Still, this is not very practical in combat. It is exclusively an assassination technique.' Rui mused.

Finding out a person's innate vibration frequency in the middle of combat was an extremely difficult task unless he created a sensory technique specifically to detect such a thing, it would take a long time.

Thankfully, he didn't need to worry about that. His goals were assassinations, not fights, thus the technique project was fine for his current needs as it was.

'I need to come up with a project name for this new technique.' Rui gave it some thought before settling on a name. 'Project Death's Sympathy.'

It sounded a bit cheesy to his ears, but it was fine. Unlike some Martial Artists, he didn't scream out the name of his techniques when using them, so no one would ever find out.

He intended to master the technique as soon as possible. In his estimation, it would serve as an incredibly powerful killing tool that could kill Martial Seniors as long as they didn't use their Martial Heart. It was limited to quasi-senior level targets, like Martial Seniors without their Martial Hearts.

That, in combination with the Void Pathfinder, would ensure that nobody would be able to directly detect or see him or his attack coming. The two techniques were extremely powerful in their own right, when combined, their synergy would produce an extraordinary result that very Martial Seniors would likely be able to replicate, if any at all.

Given that Project Death's Sympathy was a technique that was shaping up to be grade ten, he couldn't wait to master the technique. The excited feeling of anticipation and enthuse was something that he hadn't felt in a while, he realized belatedly.

The last technique that he had created was the Nemean Blossom, which felt like forever ago.

Part of the reason was that he focused on quality instead of quantity. If Rui wanted, he could easily create numerous mid-grade or even high-grade techniques. But he would rather create one powerful grade-ten technique, or at least grade-nine technique, than many inferior techniques.

It meant that each project took time and effort, not to mention inspiration. It also took powerful circumstances.

Powerful circumstances like trying to eliminate all assassins in the Shadow Isles.
